1. The contact information of this institution should be printed on the certificate.
In addition to the qualification of the institution, the back of the certificate must also have the name, contact number, address, website and other detailed information of the appraisal institution. The state has strict qualification certification for jewelry and jade quality appraisal institutions, and the appraisal certificate issued is only valid after certification.
2. The qualification of the institution shall be printed on the certificate.
There are five kinds of institutional qualification certification: CAL certification, CMA certification, CNAL certification, CNAS certification and ICLA-MRA certification. The inspection report marked "CMA" can be used for product quality evaluation, results and judicial appraisal, and has legal effect. This symbol only indicates that the organization is a unit that has passed the measurement certification review and is a necessary qualification for any unit that issues a jewelry appraisal certificate.
3. The identification items on the certificate must be printed by the machine.
The state forces the printing of identification certificates for machines, and the identification certificates filled in by hand have no reference value. If an appraisal certificate has the above five information, then the certificate is more authoritative.
4. The certificate must have a steel seal.
Generally, domestic certificates must be stamped with the steel seal of the appraisal institution when they are made, but not necessarily abroad. If the jewelry photos on the certificate are printed electronically, then the steel seal does not need to be pressed. If the photo is posted, then the steel seal must be pressed.
5. Pay attention to the contents on the certificate.
The contents of the appraisal certificate come from different testing units, and the format of the certificate may be different, but the basic contents contained therein are basically the same. Look at the date of issuance of the appraisal certificate and pay attention to the units and personnel of the certificate.
